- Makefile.m32: reintroduce CROSSPREFIX and -W -Wall [ci skip]

  - Reintroduce `CROSSPREFIX`:

    If set, we add it to the `CC` and `AR` values, and to the _default_
    value of `RC`, which is `windres`. This allows to control each of
    these individidually, while also allowing to simplify configuration
    via `CROSSPREFIX`.

    This variable worked differently earlier. Hopefully this new solution
    hits a better compromise in usefulness/complexity/flexibility.

  schannel: Don't reset recv/send function pointers on renegotiation

  These function pointers will have been set when the initial TLS
  handshake was completed. If they are unchanged, there is no need to set
  them again. If they have been changed, as is the case with HTTP/2, we
  don't want to override that change. That would result in the
  http22_recv/send functions being completely bypassed.

  While here, delete a broken check for

- cmake: set HAVE_GETADDRINFO_THREADSAFE on Windows

  autotools enables this configuration option unconditionally for Windows
  [^1]. Do the same in CMake.

  The above will make this work for all reasonably recent environments.
  The logic present in `lib/config-win32.h` [^2] has the following
  exceptions which we did not cover in this CMake update:

  - Builds targeting Windows 2000 and earlier
  - MS Visual C++ 5.0 (1997) and earlier

  Also make sure to disable this feature when `HAVE_GETADDRINFO` isn't
  set, to avoid a broken build. We might want to handle that in the C
  sources in a future commit.

- cmake: sync HAVE_SIGNAL detection with autotools

  `HAVE_SIGNAL` means the availability of the `signal()` function in
  autotools, while in CMake it meant the availability of that function
  _and_ the symbol `SIGALRM`.

  The latter is not available on Windows, but the function is, which means
  on Windows, autotools did define `HAVE_SIGNAL`, but CMake did not,
  introducing a slight difference into the binaries.

  This patch syncs CMake behaviour with autotools to look for the function
  only.

  The logic came with the initial commit adding CMake support to curl, so
  the commit history doesn't reveal the reason behind it. In any case,
  it's best to check the existence of `SIGALRM` directly in the source
  before use. For now, curl builds fine with `HAVE_SIGNAL` enabled and
  `SIGALRM` missing.

- cmake: delete duplicate HAVE_GETADDRINFO test

  A custom `HAVE_GETADDRINFO` check came with the initial CMake commit

  The custom check was also non-portable, so this patch deletes it in
  favor of the standard check.

- lib: set more flags in config-win32.h

  The goal is to add any flag that affect the created binary, to get in
  sync with the ones built with CMake and autotools.

  I took these flags from curl-for-win [0], where they've been tested with
  mingw-w64 and proven to work well.

  This patch brings them to curl as follows:

  - Enable unconditionally those force-enabled via
    `CMake/WindowsCache.cmake`:

    - `HAVE_SETJMP_H`
    - `HAVE_STRING_H`
    - `HAVE_SIGNAL` (CMake equivalent is `HAVE_SIGNAL_FUNC`)

  - Expand existing guards with mingw-w64:

    - `HAVE_STDBOOL_H`
    - `HAVE_BOOL_T`

  - Enable Win32 API functions for Windows Vista and later:

    - `HAVE_INET_NTOP`
    - `HAVE_INET_PTON`

  - Set sizes, if not already set:

    - `SIZEOF_OFF_T = 8`
    - `_FILE_OFFSET_BITS = 64` when `USE_WIN32_LARGE_FILES` is set,
      and using mingw-w64.

  - Add the remaining for mingw-w64 only. Feel free to expand as desired:

    - `HAVE_LIBGEN_H`
    - `HAVE_FTRUNCATE`
    - `HAVE_BASENAME`
    - `HAVE_STRTOK_R`

  Future TODO:

  - `HAVE_SIGNAL` has a different meaning in CMake. It's enabled when both
    the `signal()` function and the `SIGALRM` macro are found. In
    autotools and this header, it means the function only. For the
    function alone, CMake uses `HAVE_SIGNAL_FUNC`.

- http: try parsing Retry-After: as a number first

  Since the date parser allows YYYYMMDD as a date format (due to it being
  a bit too generic for parsing this particular header), a large integer
  number could wrongly match that pattern and cause the parser to generate
  a wrong value.

  No date format accepted for this header starts with a decimal number, so
  by reversing the check and trying a number first we can deduct that if
  that works, it was not a date.

- Makefile.m32: drop CROSSPREFIX and our CC/AR defaults [ci skip]

  This patch aimed to fix a regression [0], where `CC` initialization
  moved beyond its first use. But, on closer inspection it turned out that
  the `CC` initialization does not work as expected due to GNU Make
  filling it with `cc` by default. So unless implicit values were
  explicitly disabled via a GNU Make option, the default value of
  `$CROSSPREFIX` + `gcc` was never used. At the same time the implicit
  value `cc` maps to `gcc` in (most/all?) MinGW envs.

  `AR` has the same issue, with a default value of `ar`.

  We could reintroduce a separate variable to fix this without ill
  effects, but for simplicity and flexibility, it seems better to drop
  support for `CROSSPREFIX`, along with our own `CC`/`AR` init logic, and
  require the caller to initialize `CC`, `AR` and `RC` to the full
  (prefixed if necessary) names of these tools, as desired.

  We keep `RC ?= windres` because `RC` is empty by default.

  Also fix grammar in a comment.

  aws_sigv4: fix header computation

  Handle canonical headers and signed headers creation as explained here:
  https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html

  The algo tells that signed and canonical must contain at last host and
  x-amz-date.

  So we check whatever thoses are present in the curl http headers list.
  If they are, we use the one enter by curl user, otherwise we generate
  them.  then we to lower, and remove space from each http headers plus
  host and x-amz-date, then sort them all by alphabetical order.

  This patch also fix a bug with host header, which was ignoring the port.

  schannel: when importing PFX, disable key persistence

  By default, the PFXImportCertStore API persists the key in the user's
  key store (as though the certificate was being imported for permanent,
  ongoing use.)

  The documentation specifies that keys that are not to be persisted
  should be imported with the flag PKCS12_NO_PERSIST_KEY.
  NOTE: this flag is only supported on versions of Windows newer than XP
  and Server 2003.

  --

  This is take 2 of the original fix. It extends the lifetime of the
  client certificate store to that of the credential handle. The original
  fix which landed in 70d010d and was later reverted in aec8d30 failed to
  work properly because it did not do that.

  Minor changes were made to the schannel credential context to support
  closing the client certificate store handle at the end of an SSL session.

- Makefile.m32: support more options [ci skip]

  - Add support for these options:
    `-wolfssl`, `-wolfssh`, `-mbedtls`, `-libssh`, `-psl`

    Caveats:
    - `-wolfssh` requires `-wolfssl`.
    - `-wolfssl` cannot be used with OpenSSL backends in parallel.
    - `-libssh` has build issues with BoringSSL and LibreSSL, and also
       what looks like a world-writable-config vulnerability on Windows.
       Consider it experimental.
    - `-psl` requires `-idn2` and extra libs passed via
      `LIBS=-liconv -lunistring`.

  - Detect BoringSSL/wolfSSL and set ngtcp2 crypto lib accordingly.
  - Generalize MultiSSL detection.
  - Use else-if syntax. Requires GNU Make 3.81 (2006-04-01).
  - Document more customization options.

  This brings over some configuration logic from `curl-for-win`.

- cmake: enable more detection on Windows

  Enable `HAVE_UNISTD_H`, `HAVE_STRTOK_R` and `HAVE_STRCASECMP` detection
  on Windows, instead of having predefined values.

  With these features detected correctly, CMake Windows builds get closer
  to the autotools and `config-win32.h` ones.

  This also fixes detecting `HAVE_FTRUNCATE` correctly, which required
  `unistd.h`.

  Fixing `ftruncate()` in turn causes a build warning/error with legacy
  MinGW/MSYS1 due to an offset type size mismatch. This env misses to
  detect `HAVE_FILE_OFFSET_BITS`, which may be a reason. This patch
  force-disables `HAVE_FTRUNCATE` for this platform.

  curl-wolfssl.m4: error out if wolfSSL is not usable

  When I explicitly declare, that I would like to have curl built with
  wolfSSL support using `--with-wolfssl` configure option, then I would
  expect, that either I endup with curl having that support, for example
  in form of https support or it wouldn't be available at all.

  Downstream projects like for example OpenWrt build curl wolfSSL variant
  with `--with-wolfssl` already, but in certain corner cases it does fail:

    configure:25299: checking for wolfSSL_Init in -lwolfssl
    configure:25321: x86_64-openwrt-linux-musl-gcc -o conftest [snip]

    compilation terminated.

  and in the end thus produces curl without https support:

   curl: (1) Protocol "https" not supported or disabled in libcurl

  So fix it, by making the working wolfSSL mandatory and error out in
  configure step when that's not the case:

   checking for wolfSSL_Init in -lwolfssl... no
   configure: error: --with-wolfssl but wolfSSL was not found or doesn't work

- websockets: remodeled API to support 63 bit frame sizes

  curl_ws_recv() now receives data to fill up the provided buffer, but can
  return a partial fragment. The function now also get a pointer to a
  curl_ws_frame struct with metadata that also mentions the offset and
  total size of the fragment (of which you might be receiving a smaller
  piece). This way, large incoming fragments will be "streamed" to the
  application. When the curl_ws_frame struct field 'bytesleft' is 0, the
  final fragment piece has been delivered.

  curl_ws_recv() was also adjusted to work with a buffer size smaller than
  the fragment size. (Possibly needless to say as the fragment size can
  now be 63 bit large).

  curl_ws_send() now supports sending a piece of a fragment, in a
  streaming manner, in addition to sending the entire fragment in a single
  call if it is small enough. To send a huge fragment, curl_ws_send() can
  be used to send it in many small calls by first telling libcurl about
  the total expected fragment size, and then send the payload in N number
  of separate invokes and libcurl will stream those over the wire.

  The struct curl_ws_meta() returns is now called 'curl_ws_frame' and it
  has been extended with two new fields: *offset* and *bytesleft*. To help
  describe the passed on data chunk when a fragment is delivered in many
  smaller pieces.

  The documentation has been updated accordingly.

- tidy-up: delete parallel/unused feature flags

  Detecting headers and lib separately makes sense when headers come in
  variations or with extra ones, but this wasn't the case here. These were

  for a working build. This patch leaves a single macro for each of these

    a toggle to turn off that logic, called `CURL_SPECIAL_LIBZ`.

    retains it for compatibility and deprecates it.

  - Rely on `USE_LIBSSH2`, delete parallel `HAVE_LIBSSH2_H`.

    Also delete `LIBSSH2_WIN32`, `LIBSSH2_LIBRARY` from

    itself. And `CURL_USE_LIBSSH`, which had no use at all.

  After this patch, we reduce the three copies of most `Makefile.m32`

  complexity.

  `Makefile.m32` reduction:

  |                   |  bytes | LOC total |  blank |  comment |  code |
  |-------------------|-------:|----------:|-------:|---------:|------:|

  | after this patch  |  11680 |       392 |     52 |      104 |   236 |

  Details:

  - Change rules to create objects for the `v*` subdirs in the `lib` dir.
    This allows to use a shared compile rule and assumes that filenames
    are not (and will not be) colliding across these directories.
    `Makefile.m32` now also stores a list of these subdirs. They are
    changing rarely though.

  - Sync as much as possible between the three `Makefile.m32` scripts'
    rules and their source/target sections.

  - After this patch `CPPFLAGS` are all applied to the `src` sources once
    again. This matches the behaviour of cmake/autotools. Only zlib ones
    are actually required there.

  - Use `.rc` names from `Makefile.inc` instead of keeping a duplicate.

  - Change examples to link `libcurl.dll` by default. This makes building
    trivial, even as a cross-build:
      `CC=x86_64-w64-mingw32-gcc make -f Makefile.m32`
    To run them, you need to move/copy or add-to-path `libcurl.dll`.
    You can select static mode via `CFG=-static`.

  - List more of the `Makefile.m32` config variables.

  - Drop `.rc` support from examples. It made it fragile without much
    benefit.

  - Include a necessary system lib for the `externalsocket.c` example.

  - Exclude unnecessary systems libs when building in `-dyn` mode.

- Makefile.m32: major rework [ci skip]

  This patch overhauls `Makefile.m32` scripts, fixing a list of quirks,
  making its behaviour and customization envvars align better with other
  build systems, aiming for less code, that is easier to read, use and
  maintain.

  Details:
  - Rename customization envvars:
    `CURL_CC` -> `CC`
    `CURL_RC` -> `RC`
    `CURL_AR` -> `AR`
    `CURL_LDFLAG_EXTRAS_DLL` -> `CURL_LDFLAGS_LIB`
    `CURL_LDFLAG_EXTRAS_EXE` -> `CURL_LDFLAGS_BIN`
  - Drop `CURL_STRIP` and `CURL_RANLIB`. These tools are no longer used.
  - Accept `CFLAGS`, `CPPFLAGS`, `RCFLAGS`, `LDFLAGS` and `LIBS` envvars.
  - Drop `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, `CURL_RCFLAG_EXTRAS` in
    favor of the above.
  - Do not automatically enable `zlib` with `libssh2`. `zlib` is optional
    with `libssh2`.
  - Omit unnecessary `CPPFLAGS` options when building `curl.exe` and
    examples.
  - Drop support for deprecated `-winssl` `CFG` option. Use `-schannel`
    instead.
  - Avoid late evaluation where not necessary (`=` -> `:=`).
  - Drop support for `CURL_DLL_A_SUFFIX` to override the implib suffix.
    Instead, use the standard naming scheme by default: `libcurl.dll.a`.
    The toolchain recognizes the name, and selects it automatically when
    asking for a `-shared` vs. `-static` build.
  - Stop applying `strip` to `libcurl.a`. Follow-up from
    16a58e9f93c7e89e1f87720199388bcfcfa148a4. There was no debug info to
    strip since then.
  - Stop setting `-O3`, `-W`, `-Wall` options. You can add these to
    `CFLAGS` as desired.
  - Always enable `-DCURL_DISABLE_OPENSSL_AUTO_LOAD_CONFIG` with OpenSSL,
    to avoid that vulnerability on Windows.
  - Add `-lbrotlicommon` to `LIBS` when using `brotli`.
  - Do not enable `-nghttp3` without `-ngtcp2`.
  - `-ssh2` and `-rtmp` options no longer try to auto-select a TLS-backend.
    You need to set the backend explicitly. This scales better and avoids
    issues with certain combinations (e.g. `libssh2` + `wolfssl` with no
    `schannel`).
  - Default to OpenSSL TLS-backend with `ngtcp2`. Possible to override via
    `NGTCP2_LIBS`.
  - Old, alternate method of enabling components (e.g. `SSH2=1`) no longer
    supported.
  - Delete `SPNEGO` references. They were no-ops.
  - Drop support for Win9x environments.
  - Allow setting `OPENSSL_LIBS` independently from `OPENSSL_LIBPATH`.
  - Support autotools/CMake `libssh2` builds by default.
  - Respect `CURL_DLL_SUFFIX` in `-dyn` mode when building `curl.exe` and
    examples.
  - Assume standard directory layout with `LIBCARES_PATH`. (Instead of the
    long gone embedded one.)
  - Stop static linking with c-ares by default. Add
    `CPPFLAGS=-DCARES_STATICLIB` to enable it.
  - Reorganize internal layout to avoid redundancy and emit clean diffs
    between src/lib and example make files.
  - Delete unused variables.
  - Code cleanups/rework.
  - Comment and indentation fixes.

  Closes #9634

- Makefile.m32: delete legacy component bits [ci skip]

  - Drop auto-detection of OpenSSL 1.0.2 and earlier. Now always defaulting
    to OpenSSL 1.1.0 and later, LibreSSL and BoringSSL.

  - Drop `Invalid path to OpenSSL package` detection. OpenSSL has been
    using a standard file layout since 1.1.0, so this seems unnecessary
    now.

  - Drop special logic to enable Novell LDAP SDK support.

  - Drop special logic to enable OpenLDAP LDAP SDK support. This seems
    to be distinct from native OpenLDAP, with support implemented inside
    `lib/ldap.c` (vs. `lib/openldap.c`) back when the latter did not exist
    yet in curl.

  - Add `-lwldap32` only if there is no other LDAP library (either native
    OpenLDAP, or SDKs above) present.

  - Update `doc/INSTALL.md` accordingly.

  After this patch, it's necessary to make configration changes when using
  OpenSSL 1.0.2 or earlier, or the two LDAP SDKs.

  OpenSSL 1.0.2 and earlier:
  ```
  export OPENSSL_INCLUDE = <path-to-openssl>/outinc
  export OPENSSL_LIBPATH = <path-to-openssl>/out
  export OPENSSL_LIBS = -lssl32 -leay32 -lgdi32
  ```

  Novell LDAP SDK, previously enabled via `USE_LDAP_NOVELL=1`:
  ```
  export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/inc -DCURL_HAS_NOVELL_LDAPSDK
  export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib/mscvc -lldapsdk -lldapssl -lldapx
  ```

  OpenLDAP LDAP SDK, previously enabled via `USE_LDAP_OPENLDAP=1`:
  ```
  export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/include -DCURL_HAS_OPENLDAP_LDAPSDK
  export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib -lldap -llber
  ```

  I haven't tested these scenarios, and in general we recommend using
  a recent OpenSSL release. Also, WinLDAP (the Windows default) and
  OpenLDAP (via `-DUSE_OPENLDAP`) are the LDAP options actively worked on
  in curl.

  This local autotools logic was put in place in
  9e24b9c7afbcb81120af4cf3f6cdee49a06d8224 (in 2012) which disabled it for
  Windows unconditionally. Testing reveals that it actually works with

  feature on that platform. Bringing this in sync with CMake, which already
  supported this.

  Closes #9586

- autotools: reduce brute-force when detecting recv/send arg list

  autotools uses brute-force to detect `recv`/`send`/`select` argument
  lists, by interating through _all_ argument type combinations on each
  `./configure` run. This logic exists since
  01fa02d0b545e1433dced2430561f8c0c72b74a9 (from 2006) and was a bit later
  extended with Windows support.

  This results in a worst-case number of compile + link cycles as below:
  - `recv`: 96
  - `send`: 192
  - `select`: 60
  Total: 348 (the number of curl C source files is 195, for comparison)

  Notice that e.g. curl-for-win autotools builds require two `./configure`
  invocations, doubling these numbers.

  `recv` on Windows was especially unlucky because `SOCKET` (the correct
  choice there) was listed _last_ in one of the outer trial loops. This
  resulted in lengthy waits while autotools was trying all invalid
  combinations first, wasting cycles, disk writes and slowing down
  iteration.

  This patch reduces the amount of idle work by reordering the tests in
  a way to succeed first on a well-known platform such as Windows, and
  also on non-Windows by testing for POSIX prototypes first, on the
  assumption that these are the most likely candidates these days. (We do
  not touch `select`, where the order was already optimal for these
  platforms.)

  For non-Windows, this means to try a return value of `ssize_t` first,
  then `int`, reordering the buffer argument type to try `void *` first,
  then `byte *`, and prefer the `const` flavor with `send`. If we are
  here, also stop testing for `SOCKET` type in non-Windows builds.

  After the patch, detection on Windows is instantaneous. It should also be
  faster on popular platforms such as Linux and BSD-based ones.

  If there are known-good variations for other platforms, they can also be
  fast-tracked like above, given a way to check for that platform inside
  the autotools logic.

  CURLOPT_REDIR_PROTOCOLS_STR.

  Rather than using the CURLPROTO_* constants, dynamically assign protocol
  numbers based on the order they are listed by curl_version_info().

  New type proto_set_t implements prototype bit masks: it should therefore
  be large enough to accomodate all library-enabled protocols. If not,
  protocol numbers beyond the bit count of proto_set_t are recognized but
  "inaccessible": when used, a warning is displayed and the value is
  ignored. Should proto_set_t overflows, enabled protocols are reordered to
  force those having a public CURLPROTO_* representation to be accessible.

  Code has been added to subordinate RTMP?* protocols to the presence of
  RTMP in the enabled protocol list, being returned by curl_version_info()
  or not.

  setopt: use the handler table for protocol name to number conversions

  This also returns error CURLE_UNSUPPORTED_PROTOCOL rather than
  CURLE_BAD_FUNCTION_ARGUMENT when a listed protocol name is not found.

  A new schemelen parameter is added to Curl_builtin_scheme() to support
  this extended use.

  Note that disabled protocols are not recognized anymore.

  Tests adapted accordingly.

  The parser now checks that the scheme is known before it counts slashes,
  to improve the error messge for URLs with unknown schemes and maybe no

  wolfSSL: fix session management bug.

  Prior to this commit, non-persistent pointers were being used to store
  sessions.  When a WOLFSSL object was then freed, that freed the session
  it owned, and thus invalidated the pointer held in curl's cache. This
  commit makes it so we get a persistent (deep copied) session pointer

  content_encoding: use writer struct subclasses for different encodings

  The variable-sized encoding-specific storage of a struct contenc_writer
  currently relies on void * alignment that may be insufficient with
  regards to the specific storage fields, although having not caused any
  problems yet.

  In addition, gcc 11.3 issues a warning on access to fields of partially
  allocated structures that can occur when the specific storage size is 0:

    content_encoding.c: In function ‘Curl_build_unencoding_stack’:
    content_encoding.c:980:21: warning: array subscript ‘struct contenc_writer[0]’ is partly outside array bounds of ‘unsigned char[16]’ [-Warray-bounds]
      980 |     writer->handler = handler;
          |     ~~~~~~~~~~~~~~~~^~~~~~~~~
    In file included from content_encoding.c:49:
    memdebug.h:115:29: note: referencing an object of size 16 allocated by ‘curl_dbg_calloc’
      115 | #define calloc(nbelem,size) curl_dbg_calloc(nbelem, size, __LINE__, __FILE__)
          |                             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    content_encoding.c:977:60: note: in expansion of macro ‘calloc’
      977 |   struct contenc_writer *writer = (struct contenc_writer *)calloc(1, sz);

  To solve both these problems, the current commit replaces the
  contenc_writer/params structure pairs by "subclasses" of struct
  contenc_writer. These are structures that contain a contenc_writer at
  offset 0. Proper field alignment is therefore handled by the compiler and
  full structure allocation is performed, silencing the warnings.

  for agreeing to use the SPDY protocol (the precursor to HTTP/2) for

  curl supports the NPN extension with some TLS backends since then, with

  HTTP/2 proper is made to use the ALPN (Application-Layer Protocol
  Negotiation) extension and the NPN extension has no purposes
  anymore. The HTTP/2 spec was published in May 2015.

  CURLOPT_WILDCARDMATCH.3: Fix backslash escaping under single quotes

   Lintian (on Debian) has been complaining about this for a while but
   I didn't bother initially as the groff parser that we use is not
   affected by this.

   But I have now noticed that the online manpage is affected by it:
   https://curl.se/libcurl/c/CURLOPT_WILDCARDMATCH.html

   (I'm using double quotes for quoting-only down below)

   The section that should be parsed as "'\'" ends up being parsed as
   "'´".

   This is due to roffit not parsing "'\\'" correctly, which is fine
   as the "correct" way of writing "'\'" is "'\e'" instead.

   Note that this fix is not enough to fix the online manpage at
   curl's website, as roffit seems to parse it wrongly either way.

   My intent is to at least fix the manpage so that roffit can
   be changed to parse "'\e'" correctly (although I suggest making
   roffit parse both ways correctly, since that's what groff does).

- cmake: fix original MinGW builds

  1. Re-enable `HAVE_GETADDRINFO` detection on Windows

     Commit d08ee3c83d6bd416aef62ff844c98e47c4682429 (in 2013) added logic
     that automatically assumed `getaddrinfo()` to be present for builds
     with IPv6 enabled. As it turns out, certain toolchains (e.g. original
     MinGW) by default target older Windows versions, and thus do not
     support `getaddrinfo()` out of the box. The issue was masked for
     a while by CMake builds forcing a newer Windows version, but that
     logic got deleted in commit 8ba22ffb2030ed91312fc8634e29516cdf0a9761.
     Since then, some CI builds started failing due to IPv6 enabled,
     `HAVE_GETADDRINFO` set, but `getaddrinfo()` in fact missing.

     It also turns out that IPv6 works without `getaddrinfo()` since commit
     67a08dca27a6a07b36c7f97252e284ca957ff1a5 (from 2019, via #4662). So,
     to resolve all this, we can now revert the initial commit, thus
     restoring `getaddrinfo()` detection and support IPv6 regardless of its
     outcome.

  2. Omit `bcrypt` with original MinGW

     Original (aka legacy/old) MinGW versions do not support `bcrypt`
     (introduced with Vista). We already have logic to handle that in
     `lib/rand.c` and autotools builds, where we do not call the
     unsupported API and do not link `bcrypt`, respectively, when using
     original MinGW.

     This patch ports that logic to CMake, fixing the link error:
     `c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: cannot find -lbcrypt`

  url: really use the user provided in the url when netrc entry exists

  If the user is specified as part of the URL, and the same user exists
  in .netrc, Authorization header was not sent at all.

  The user and password fields were assigned in conn->user and password
  but the user was not assigned to data->state.aptr, which is the field
  that is used in output_auth_headers and friends.

  Fix by assigning the user also to aptr.

  If netrc entry has password with empty login, use it for any username.

  Example:

- Makefile.m32: allow -nghttp3/-ngtcp2 without -ssl [ci skip]

  Before this patch `-nghttp3`/`-ngtcp2` had an effect only when `-ssl`
  was also enabled. `-ssl` meaning OpenSSL (and its forks). After
  8a13be227eede2601c2b3b1c63e08b3dc9b35dd5 nghttp3/ngtcp2 can also be
  used together with wolfSSL. This patch adds the ability to enable
  `-nghttp3`/`-ngtcp2` independently from `-ssl` (OpenSSL), allowing to
  use it with wolfSSL or other, future TLS backends.

  Before this patch, it was fine to enable `-nghttp3`/`-ngtcp2`
  unconditionally. After this patch, this is no longer the case, and now
  it's the user's responsibility to enable `-nghttp3`/`-ngtcp2` only
  together with a compatible TLS backend.

  When using a TLS backend other than OpenSSL, the TLS-specific ngtcp2
  library must be configured manually, e.g.:
    `export CURL_LDFLAG_EXTRAS=-lngtcp2_crypto_wolfssl`

  (or via `NGTCP2_LIBS`)

  docs: add dns category to --resolve

  This commit adds the dns category to the --resolve command line option,
  because it can be interpreted as both: a low-level connection option and
  an option related to the resolving of a hostname.

  It is also not common for dns options to belong to the connection
  category and vice versa.  --ipv4 and --ipv6 are both good examples.

  cmdline-opts/gen.pl: improve performance

  On some systems, the gen.pl script takes nearly two minutes for the
  generation of the main-page, which is a completely unacceptable time.

  The slow performance has two causes:
  1. Use of a regex locale operator
  2. Useless invokations of loops

  The commit addresses the first issue by replacing the "\W" wiht
  [^a-zA-Z0-9_], which is, according to regex101.com, functionally
  equivalent to the previous operation, except that it is obviously
  limited to ASCII only, which is fine, as the curl project is
  English-only anyway.

  The second issue is being addressed by only running the loop if the line
  contains a "--" in it. The loop may be completeley removed in the
  future.

  curl-functions.m4: check whether atomics can link rather than just compile

  Some build toolchains support C11 atomics (i.e., _Atomic types), but
  will not link the associated atomics runtime unless a flag is passed. In
  such an environment, linking an application with libcurl.a can fail due
  to undefined symbols for atomic load/store functions.

  I encountered this behavior when upgrading curl to 7.84.0 and attempting
  to build with Solaris Studio 12.6. Solaris provides the flag
  -xatomic=[gcc | studio], allowing users to link to one of two atomics
  runtime implementations. However, if the user does not provide this
  flag, then neither runtime is linked. This led to builds failing in CI.

- Makefile.m32: stop trying to build libcares.a [ci skip]

  Before this patch, `lib/Makefile.m32` had a rule to build `libcares.a` in
  `-cares`-enabled builds, via c-ares's own `Makefile.m32`. Committed in
  2007 [1]. The commit message doesn't specifically address this particular
  change. This logic comes from the times when c-ares was part of the curl
  source tree, hence the special treatment.

  This feature creates problems when building c-ares first, using CMake
  and pointing `LIBCARES_PATH` to its install prefix, where `Makefile.m32`
  is missing in such case. A sub-build for c-ares is undesired also when
  c-ares had already been build via its own `Makefile.m32`.

  To avoid the sub-build, this patch deletes its Makefile rule. After this
  patch `libcares.a` needs to be manually built before using it in
  `Makefile.m32`. Aligning it with the rest of dependencies.

- build: improve OS string in CMake and `config-win32.h`

  This patch makes CMake fill the "OS string" with the value of
  `CMAKE_C_COMPILER_TARGET`, if passed. This typically contains a triplet,
  the same we can pass to `./configure` via `--host=`.

  For non-CMake, non-autotools, Windows builds, this patch adds the ability
  to override the default `OS` value in `lib/config-win32.h`.

  With these its possible to get the same OS string across the three build
  systems.

  This patch supersedes the earlier, partial, CMake-only solution:
  435f395f3f8c11eebfcc243ca55ebcc11a19b8b8, thus retiring the
  `CURL_OS_SUFFIX` CMake option.

  `CURL_RC` comes handy when using LLVM tools with `CROSSPREFIX=llvm-` and
  `CURL_CC=clang` set on current latest debian:unstable or earlier, where
  `llvm-windres` is missing, and a `CURL_RC=<triplet>-windres` fixes it.
  Hopefully this will be fixed in the llvm package. FWIW `llvm-windres`
  does exist in Homebrew llvm, MSYS2 llvm and llvm-mingw.

  BoringSSL doesn't keep a version number, and doesn't self-identify itself

  BoringSSL revisions by their commit hash. This hash is typically known by
  the builder. This patch adds a way to pass this hash to libcurl, so that
  it can display in the curl version string:

  For example:

  `CFLAGS=-DCURL_BORINGSSL_VERSION="c239ffd0"`

  ```
  curl 7.84.0 (x86_64-w64-mingw32) libcurl/7.84.0 BoringSSL/c239ffd0 (Schannel) zlib/1.2.12 [...]
  Release-Date: 2022-06-27
  Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap ldaps mqtt pop3 [...]
  Features: alt-svc AsynchDNS brotli gsasl HSTS HTTP2 HTTP3 HTTPS-proxy IDN IPv6 Kerberos [...]
  ```

  The setting is optional, and if not passed, BoringSSL will appear without
  a version number, like before this patch.

- makefile.m32: add support for custom ARCH [ci skip]

  When building curl for target platform other than x64 and x86, it is now
  possible to pass `ARCH=custom`, that will omit all hardcoded logic for
  setting up CFLAGS/LDFLAGS/RCFLAGS for these platforms, and let these be
  customized via `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, and a newly
  added one for the resource compiler: `CURL_RCFLAG_EXTRAS`.

  This makes it possible to use `makefile.m32` to build for ARM64 for
  example.

- cmake: do not force Windows target versions

  The goal of this patch is to avoid CMake forcing specific Windows
  versions and rely on toolchain defaults or manual selection instead.
  This gives back control to the user. This also brings CMake closer to
  how autotools and `Makefile.m32` behaves in this regard.

  - CMake had a setting `ENABLE_INET_PTON` defaulting to `ON`, which did
    nothing else than fixing the Windows build target to Vista. This also
    happened when the toolchain did not have Vista support (e.g. original
    MinGW), breaking such builds.

    In other environments it did not make a user-facing difference,
    because libcurl has its own pton() implementation, so it works well
    with or without Vista's inet_pton().

    This patch drops this setting. inet_pton() is now used whenever
    building for Vista or newer, either when requested manually or by
    default with modern toolchains (e.g. mingw-w64). Older envs will fall
    back to curl's pton().

    Ref: https://github.com/curl/curl/pull/9027#issuecomment-1164157604
    Ref: https://github.com/curl/curl/pull/8997#issuecomment-1164344155

  - When the user did no select a Windows target version manually, stop
    explicitly targeting Windows XP, and instead use the toolchain default.

    This may pose an issue with old toolchains defaulting to pre-XP
    targets. In such case you must manually target Windows XP via:
      `-DCURL_TARGET_WINDOWS_VERSION=0x0501`
    or
      `-DCMAKE_C_FLAGS=-D_WIN32_WINNT=0x0501`

- windows: improve random source

  - Use the Windows API to seed the fallback random generator.

    This ensures to always have a random seed, even when libcurl is built
    with a vtls backend lacking a random generator API, such as rustls
    (experimental), GSKit and certain mbedTLS builds, or, when libcurl is
    built without a TLS backend. We reuse the Windows-specific random
    function from the Schannel backend.

  - Implement support for `BCryptGenRandom()` [1] on Windows, as a
    replacement for the deprecated `CryptGenRandom()` [2] function.

    It is used as the secure random generator for Schannel, and also to
    provide entropy for libcurl's fallback random generator. The new
    function is supported on Vista and newer via its `bcrypt.dll`. It is
    used automatically when building for supported versions. It also works
    in UWP apps (the old function did not).

  - Clear entropy buffer before calling the Windows random generator.

    This avoids using arbitrary application memory as entropy (with
    `CryptGenRandom()`) and makes sure to return in a predictable state
    when an API call fails.

  ftp: restore protocol state after http proxy CONNECT

  connect_init() (lib/http_proxy.c) swaps out the protocol state while
  working on the proxy connection, this is then restored by
  Curl_connect_done() after the connection completes.

  ftp_do_more() extracted the protocol state pointer to a local variable
  at the start of the function then calls Curl_proxy_connect(). If the proxy
  connection completes, Curl_proxy_connect() will call Curl_connect_done()
  (via Curl_proxyCONNECT()), which restores data->req.p to point to the ftp
  protocol state instead of the http proxy protocol state, but the local
  variable in ftp_do_more still pointed to the old value.

  Ultimately this meant that the state worked on by ftp_do_more() was the
  http proxy state not the ftp state initialised by ftp_connect(), but
  subsequent calls to any ftp_ function would use the original state.

  For my use-case, the visible consequence was that ftp->downloadsize was
  never set and so downloaded data was never returned to the application.

  This commit updates the ftp protocol state pointer in ftp_do_more() after
  Curl_proxy_connect() returns, ensuring that the correct state pointer is
  used.

- rand: stop detecting /dev/urandom in cross-builds

  - Prevent CMake to auto-detect /dev/urandom when cross-building.
    Before this patch, it would detect it in a cross-build scenario on *nix
    hosts with this device present. This was a problem for example with
    Windows builds, but it could affect any target system with this device
    missing. This also syncs detection behaviour with autotools, which also
    skips it for cross-builds.
  - Also, make sure to never use the file RANDOM_FILE as entropy for libcurl's
    fallback random number generator on Windows. Windows does not have the
    concept of reading a random stream from a filename, nor any guaranteed
    non-world-writable path on disk. With this, a manual misconfiguration or
    an overeager auto-detection can no longer result in a user-controllable
    seed source.

- Makefile.m32: stop forcing XP target with ipv6 enabled [ci skip]

  Since this [1] commit in 2011, `_WIN32_WINNT` was set fixed to Windows
  XP when the `-ipv6` option is selected. Maybe this was added to support
  pre-XP Windows versions (?). These days libcurl builds fine for both XP
  and post-XP versions with IPv6 support enabled. The relevance of pre-XP
  version is also low by now. Other build methods also do not impose such
  limitation for a similar configuration. So, drop this hard-wired
  `_WIN32_WINNT` limit from `Makefile.m32`, thus building for the default
  Windows version set by the compiler. This is Vista for recent MinGW
  versions.

  Old behaviour can be restored by setting this envvar:
  export CURL_CFLAG_EXTRAS=-D_WIN32_WINNT=0x0501

- version: rename threadsafe-init to threadsafe

  Referring to Daniel's article [1], making the init function thread-safe
  was the last bit to make libcurl thread-safe as a whole. So the name of
  the feature may as well be the more concise 'threadsafe', also telling
  the story that libcurl is now fully thread-safe, not just its init
  function. Chances are high that libcurl wants to remain so in the
  future, so there is little likelihood of ever needing any other distinct
  `threadsafe-<name>` feature flags.

  For consistency we also shorten `CURL_VERSION_THREADSAFE_INIT` to
  `CURL_VERSION_THREADSAFE`, update its description and reference libcurl's
  thread safety documentation.

  digest: unquote realm and nonce before processing

  RFC 7616 (and 2617) requires values to be "unquoted" before used for
  digest calculations. The only place where unquoting can be done
  correctly is header parsing function (realm="DOMAIN\\host" and
  realm=DOMAN\\host are different realms).

  This commit adds unquoting (de-escaping) of all values during header
  parsing and quoting of the values during header forming. This approach
  should be most straightforward and easy to read/maintain as all values
  are processed in the same way as required by RFC.

- netrc: support quoted strings

  The .netrc parser now accepts strings within double-quotes in order to
  deal with for example passwords containing white space - which
  previously was not possible.

  A password that starts with a double-quote also ends with one, and
  double-quotes themselves are escaped with backslashes, like \". It also
  supports \n, \r and \t for newline, carriage return and tabs
  respectively.

  If the password does not start with a double quote, it will end at first
  white space and no escaping is performed.

  WARNING: this change is not entirely backwards compatible. If anyone
  previously used a double-quote as the first letter of their password,
  the parser will now get it differently compared to before. This is
  highly unfortunate but hard to avoid.

  15%. In total, the changes make Curl_strcasecompare() around 1.6 to 1.7
  times faster.

  Note that these optimisation assume ASCII. The original
  Curl_raw_toupper() and raw_tolower() look like they already made that
  assumption.

  This change removes adding an include `$prefix/wolfssl` or similar to

- FAQ: Clarify Windows double quote usage

  - Windows command prompt doesn't use literal quoting via single quotes.

  - Windows command prompt inner double quotes are escaped with a
    backslash.

  - Windows powershell does use single quotes but curl is not a powershell
    script so the arguments may not be passed on correctly.

  - Windows powershell inner double quotes seems can be passed to curl if
    the outer quotes are double quotes and an escape of backslash-backtick
    is used.

  Command prompt example:

  ~~~
  getargs -v -d "\"a\""

  argv[0]: getargs
  argv[1]: -v
  argv[2]: -d
  argv[3]: "a"
  ~~~

  This function has been unused since the initial commit of the GSKit

  a user pointer to this callback, which precludes the possibility to
  associate the cert chain with a data/conn structure.

  https://www.ibm.com/docs/api/v1/content/ssw_ibm_i_71/apis/gsk_attribute_set_callback.htm

- cookies: Improve errorhandling for reading cookiefile

  The existing programming had some issues with errorhandling for reading
  the cookie file. If the file failed to open, we would silently ignore it
  and continue as if there was no file (or stdin) passed. In this case, we
  would also call fclose() on the NULL FILE pointer, which is undefined
  behavior. Fix by ensuring that the FILE pointer is set before calling
  fclose on it, and issue a warning in case the file cannot be opened.
  Erroring out on nonexisting file would break backwards compatibility of
  very old behavior so we can't really go there.

  tool_paramhlp: use feof(3) to identify EOF correctly when using fread(3)

  This loop was using the number of bytes read from the file as condition
  to keep reading.

  From Linux's fread(3) man page:
  > On success, fread() and fwrite() return the number of items read or
  > written. This number equals the number of bytes transferred only when
  > size is 1. If an error occurs, or the end of the file is reached, the
  > return value is a short item count (or zero).
  >
  > The file position indicator for the stream is advanced by the number
  > of bytes successfully read or written.
  >
  > fread() does not distinguish between end-of-file and error, and
  > callers must use feof(3) and ferror(3) to determine which occurred.

  This means that nread!=0 doesn't make much sense as an end condition for
  the loop: nread==0 doesn't necessarily mean that EOF has been reached or
  an error has occured (but that is usually the case) and nread!=0 doesn't
  necessarily mean that EOF has not been reached or that no read errors
  have occured. feof(3) and ferror(3) should be uses when using fread(3).

  Currently curl has to performs an extra fread(3) call to get a return
  value equal to 0 to stop looping.

  This usually "works" (even though nread==0 shouldn't be interpreted as
  EOF) if stdin is a pipe because EOF usually marks the "real" end of the
  stream, so the extra fread(3) call will return immediately and the extra
  read syscall won't be noticeable:

      bash-5.1$ strace -e read curl -s -F file=@- 0x0.st <<< a 2>&1 |
      > tail -n 5
      read(0, "a\n", 4096)                    = 2
      read(0, "", 4096)                       = 0
      read(0, "", 4096)                       = 0
      http://0x0.st/oRs.txt
      +++ exited with 0 +++
      bash-5.1$

  But this doesn't work if curl is reading from stdin, stdin is a
  terminal, and the EOF is being emulated using a shell with ^D. Two
  consecutive ^D will be required in this case to actually make curl stop
  reading:

      bash-5.1$ curl -F file=@- 0x0.st
      a
      ^D^D
      http://0x0.st/oRs.txt
      bash-5.1$

  A possible workaround to this issue is to use a program that handles EOF
  correctly to indirectly send data to curl's stdin:

      bash-5.1$ cat - | curl -F file=@- 0x0.st
      a
      ^D
      http://0x0.st/oRs.txt
      bash-5.1$

  This patch makes curl handle EOF properly when using fread(3) in
  file2memory() so that the workaround is not necessary.

  Since curl was previously ignoring read errors caused by this fread(3),
  ferror(3) is also used in the condition of the loop: read errors and EOF
  will have the same meaning; this is done to somewhat preserve the old
  behaviour instead of making the command fail when a read error occurs.

  There is no such MSVC version (yet) as VC15 or VC17.

  For VS 2017 for example, the name we use is correct as either VS17,

- mk-ca-bundle.pl: Use stricter logic to process the certificates

  .. and bump version to 1.29.

  This change makes the script properly ignore unknown blocks and
  otherwise fail when Mozilla changes the certdata format in ways we
  don't expect. Though this is less flexible behavior it makes it far less
  likely that an invalid certificate can slip through.

  Prior to this change the state machine did not always properly reset,
  and it was possible that a certificate marked as invalid could then
  later be marked as valid when there was conflicting trust info or
  an unknown block was erroneously processed as part of the certificate.

- http: reject header contents with nul bytes

  They are not allowed by the protocol and allowing them risk that curl
  misbehaves somewhere where C functions are used but won't work on the
  full contents. Further, they are not supported by hyper and they cause
  problems for the new coming headers API work.

  Updated test 262 to verify and enabled it for hyper as well

- libssh: Improve fix for missing SSH_S_ stat macros

  - If building libcurl against an old libssh version missing SSH_S_IFMT
    and SSH_S_IFLNK then use the values from a supported version.

  Prior to this change if libssh did not define SSH_S_IFMT and SSH_S_IFLNK
  then S_IFMT and S_IFLNK, respectively, were used instead. The problem
  with that is the user's S_ stat macros don't have the same values across
  platforms. For example Windows has values different from Linux.

  Follow-up to 7b0fd39.

- tool and tests: force flush of all buffers at end of program

  On Windows data can be lost in buffers in case of abnormal program
  termination, especially in process chains as seen due to flaky tests.
  Therefore flushing all buffers manually should avoid this data loss.

  In the curl tool we play the safe game by only flushing write buffers,
  but in the testsuite where we manage all buffers, we flush everything.

  This should drastically reduce Windows CI and testsuite flakiness.

  mk-ca-bundle.vbs: delete this script in favor of mk-ca-bundle.pl

  mk-ca-bundle.vbs is a Windows-specific script for Mozilla certificate
  extraction, similar to mk-ca-bundle.pl which runs on any platform. The
  vbs version has not been maintained while the perl version has been
  maintained with improvements and security fixes. I don't think it's
  worth the work to maintain both versions. Windows users should be able
  to use mk-ca-bundle.pl without any problems, as long as they have perl.

  configure.ac: move -pthread CFLAGS setting back where it used to be

  The fix for #8276 proposed in #8374 set `CFLAGS="$CFLAGS -pthead"`
  earlier than it used to be set, applying it in cases where it should not
  have been applied.

  This moves the AIX XLC check to a new `case $host in` block inside of
  the `if test "$USE_THREADS_POSIX" != "1"` block, where `CFLAGS="$CFLAGS
  -pthead"` used to happen.
